Wheels

The definition of "road cycling" now includes gravel and dirt as well as pavement. At the same time, bikes are evolving to meet the fit requirements of smaller riders. Meeting these two distinct needs was the driving force behind the Zipp 303 Firecrest 650B Tubeless Disc-brake wheelset. The smaller rim size provides room within frames and forks for larger tires that deliver increased comfort, compliance, and cornering performance. With more tire between the rim and the ground, the overall wheel diameter, including the tire, is similar to a standard 700c wheel and road tire combination. Back on the pavement, the 650B is a better-fitting wheel for smaller athletes riding compatible frames. For too long, many smaller cyclists have trained and raced on standard 700c wheels, losing out on the advantages of a proper fitting wheel such as improved handling and the elimination of front wheel-toe overlap. At the center of the 303 650B Firecrest Tubeless is a versatile and durable hubset, the German-engineered ZR1 DB. - Zipp graphics and cosmetic identity that scream speed - Versatile 45mm rim profile for increased speed and better cornering, control, and comfort - Tubeless design provides secure performance when ridden at lower tire pressures - ZR1 DB hubset is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement - Built with Sapim CX Sprint J-bend spokes - Center Lock rotor interface (lockring included) - Ships with 12mm end caps

The new SLR 1 50 Disc WheelSystem combines aerodynamic efficiency and minimized power loss in a lightweight package designed for versatile road performance. The SLR 1 50 features 50mm aero rim profiles for efficiency on the flats and a dynamic ride quality on hillier roads. Hookless rims with a broad inner width offer greater support for high-volume tires along with enhanced sidewall stiffness for better grip and cornering. FEATURES - Wind-tunnel-proven 50mm Hookless Aero Rim Profile provides a maximum aerodynamic advantage - High tensile strength carbon fiber is placed at only the most crucial points to provide optimal stiffness and class-leading weight - Hookless rim design saves weight and creates a broad 22.4mm inner rim width for increased actual tire contact patch, resulting in better traction and compliance - A thick rim bead of up to 3.8mm on each side enhances rim bead stiffness, offering increased support for better cornering - Dynamic Balanced Lacing (DBL) technology makes a stiffer, more efficient wheel as a wider hub flange increases spoke bracing angles for outstanding power transmission - Low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance and minimizing power loss SPECIFICATIONS - Tubeless: Giant Tubeless System (rim tape and valve kit included) - Suggested Tire Size: 700 x 25C – 700 x 32C - Rim Height: 50mm - ETRTO: 622-22 - Hub Compatibility: Shimano HG, SRAM XDR (XDR driver sold separately) - Bearing: Sealed Cartridge - Weight (Front): 703g

Zipp's 3ZERO MOTO carbon 27.5 and 29 enduro/trail wheelset is inspired by moto to provide riders with the control and durability required for pure trail speed. Already this wheelset and its MOTO Technology are proven with multiple victories in the Enduro World Series with our pioneering partnership with Lapierre Zipp Collective. While other wheel brands limit their focus to traditional box-section rim designs, Zipp engineers-uninhibited by legacy technology-took a different approach. They looked to motorsports as a model. Zipp's Moto Technology's single-wall rim is the optimal approach for an enduro/trail wheelset. The resulting rim provides something we call "ankle compliance." Imagine a runner rounding a sharp turn, the ankle naturally flexing to maintain grip as the runner leans. The 3ZERO rim can locally flex to stay parallel to the ground during cornering, increasing traction like a human ankle adjusts while running. This ability to twist locally allows it to deflect during single bead impacts without the rider getting bounced offline. 3ZERO MOTO helps you take the most direct route, saving seconds when and where they count most. At the center of the 3ZERO MOTO is the ZM2 hubset. This German-engineered hubset features 12 pawls and 132 points of engagement for a quicker response. The hub's improved seal design means better durability on rough terrain. Quarq's TireWiz is an add-on option for 3ZERO to dial in your pressure for an even more compliant ride. Zipp's Speed Line graphics give you the choice of five colors for a wheel with high-performance aesthetics. - Higher impact resistance - Reduced chance of pinch flatting - More traction in rough corners - Smoother ride in rocky terrain - Ability to run lower tire pressure - Reduced rider fatigue - Frustration-free tire installation - Rim is designed for compliance, creating the feel of extra suspension - German-engineered hubset features 12 pawls and 132 points of engagement for quicker response and also has improved durability - Lifetime Warranty

Zipp's 353 NSW Tubeless Disc-brake wheel is the pinnacle of our pursuit of versatility and speed. This wheel fuses Zipp's two most advanced approaches, Sawtooth rim profile and TSE, for an all-encompassing approach to performance. With its undulating 45mm-deep rim shape, the 353 NSW provides speed on every terrain with best-in-class aerodynamic efficiency and crosswind stability. The 353 NSW is Zipp's lightest tubeless wheelset yet, making it a fast-puncher ready to fight its way into the breakaway. Zipp's use of a hookless (straight side) rim in the 353 NSW is integral to achieving our mission of Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp's hookless rims have more efficient resin distribution, which means lighter wheels. They also are highly durable. Zipp's 353 NSW's Sawtooth rim shape with Hyperfoils optimizes aerodynamic efficiency and crosswind stability. The Sawtooth design also allows the rim to be structurally strong but light. That will help you snap out of corners and maintain that speed no matter the terrain, especially in the steep, punchy stuff. The 353 NSW utilizes Zipp's Total System Efficiency, or TSE, approach to wheel design: overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The wheel's 25mm internal width is ideal for running wider tubeless tires at reduced air pressure for a more efficient ride. At the center of the 353 NSW is the Cognition V2 Hubset, re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement and lower friction, as well as improved durability. - Versatile endurance wheel for the modern road bike with tubeless and hookless rim profile - Our lightest tubeless wheel yet, making it a fast-puncher ready to fight - Optimized tire bed for easy tire installation - TSE for greater efficiency and reduced rolling resistance - Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stable performance with an undulating rim depth - Cognition V2 hubset rolls efficiently whether you are pedaling or coasting.

Superior hookless rim structure and a 30mm inner width makes the XCR 1 30 incredibly durable. And its best-in-class weight (1456g) makes it lightning fast. - 30mm inner width offers increased support for wider tires, improving stability under hard cornering and when tackling technical terrain. - Hookless rim technology offers consistent carbon fiber structure as rim bead reinforcement widens the tops of the rim sidewalls to 3.5mm, dispersing impact load and increasing durability. - Optimized carbon lay-up places high-tensile strength carbon fiber at only the most crucial points, creating an exceptionally solid rim structure without adding weight. - Dynamic Balanced Lacing technology makes a more efficient wheel that allows riders to accelerate faster and maintain maximum power transfer.

The SLR 2 36 Disc brings the performance gains of a stiff, lightweight carbon wheel to more riders everywhere. Light enough for all-day challenges through the mountains but strong and durable for daily training on variable terrain, the SLR 2 36 Disc’s optimized carbon layup contributes to significant weight reduction for better climbing as Giant hookless technology offers a wide inner rim width for a more confident ride.
